SAMUEL H. HARRINGTON, OF NEW YORK, N. Y., ASSIGNOR TO WILLIAM (3.WILSON, OF NYAOK, NEW YORK.

RAILWAY SAFETY DEVICE.

To all whom it may concern:

Be it known that I, SAMUEL H. HARRING- TON, residing at New York, in thecounty of New York and. State of New York, have invented certain new anduseful Improvements in Railway Safety Devices, of which the following isa full, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to railway safety devices.

One of the objects thereof is to provide an automatic safety appliancesuch as will insure the effectiveness of a danger signal.

Another object is the provision of apparatus whereby any danger signalwill leave a distinctive mark upon any car or train attempting to runpast the same.

Other objects will be in part obvious and in part hereinafter pointedout.

The invention proposes, broadly, the suspension at a semaphore or othersignal of a printing device of distinctive configuration peculiar tothat signal and adapted when the signal is in danger position tocooperate with recording surfaces carried by cars and leave animpression upon the recording surface of any car attempting to pass thesignal of the distinctive number or symbol of the same. Also, it isproposed to utilize the mutual reaction of the printing device and therecording surface with which it contacts to apply the brakes of the carand notify the train despatcher or other person that the signal has beenpassed.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will behereinafter described and the scope of the application thereof indicatedin the claims.

In the accompanying drawings which show one embodiment of my invention,various others of which will be readily suggested Figure 1 is anelevation of the safety mechanism constructed in accordance with thisinvention, in operative position, showing the relation thereto of theparts carried by the car. Fig. 2 is a similar view showing the parts ininoperative position. Fig. 3 is a view of a rolling member or carriagewith a part of the lever upon which it is adapted to roll. Fig. 4 is adetail view of an electric call box with the associated parts. Fig. 5 isan elevation of the plate carried by a car before Specification ofLetters Patent.

contact with the printing device. Fig. 6 is an end elevation of the sameafter contact. Fig. 7 is a view showing a preferred arrangement of ballsarranged to outline various symbols which may designate the severalnumerals associated therewith.

Similar reference characters refer to similar parts throughout theseveral views.

Referring now to Fig. 1, A represents a post or support upon which ismounted semaphore B. By the word semaphore as used throughout thisdescription andthe following claims is meant any danger signal theoperation of which involves mechanically moving parts. This semaphore isactuated in accordance with the operation of any desired system ofsignaling, not described herein as it forms no part of the presentinvention. Pivotally mounted upon support A by means of a bracket 1 is alever 2. The word lever as used throughout this specification and in thefollowing claims is used broadly to designate a lever of any class, thatis, irrespective of the relative positions of fulcrum, weight and power,and also irrespective of whether it is a rigid member or a flexiblemember held rigid by weights or other means. The inner end of saidlever, that is, the end toward support A, is adapted to be given alimited vertical movement by the semaphore, it being depressed when thelatter is in a position indicating safety and permitted to rise upon thesemaphore assuming a danger position. "With the common type of semaphoreshown in Figs. 1 and 2, an eccentrio 3 is rigidly mounted upon the arm.thereof at the pivotal point and is adapted to co act with an upwardlydisposed, inwardly curved arm l firmly secured to the inner end of lever2. This eccentric is given such an angular position with reference tothe semaphore arm that upon the latter assuming a horizontal position,customarily denoting danger, the eccentric will permit arm 1 to riseand, conversely, upon the falling of the semaphore arm, arm 4 will bedepressed.

Mounted upon the outer arm of lever 12 and adapted to roll upon the samebetween collars 2 and 2 is a carriage C. This carriage is formed of twoside members 5 adjustably secured at the bottom by means of bolts 6 andjoined at the top by rollers 7. The faces of these rollers are groovedwith a radius of curvature equal to that of the round outer arm of lever2 and the side members are bent so as to inclose this arm withoutcontact therewith. It will thus be seen that the earriage C is adaptednot only to travel along this arm but also to have a rotary movementabout the axis thereof. One of the side members 5 projects in alongitudinal direction beyond the other side member forming a shoulder 8for a purpose hereinafter explained.

Suspended from carriage C is a printing device, preferably formed of aplurality of hollow rubber balls 9 each of which is perforated, as shownat 10. The preferred means of suspension is by heavy flexible wiresclamped between the members 5 of carriage C by means of bolts 6. Balls 9contain some pigment preferably composed of lampblack and oil, thoughobviously any other marking means could be employed. The openings 10 arefilled with wicking or waste, or other means whereby the marking fluidmay be transmitted to the recording surface. The lower balls on eachwire are given sufficient weight to insure the operation of thecooperating parts hereinafter described. The balls at each semaphore arearranged in a distinctive outline. As the number of semaphores may belarge, it has been found expedient to arrange the balls to representnumerals in accordance with an arbitrary code, and that shown in Fig. 7has been found to be peculiarly adapted for this purpose owing to theabsence of curves and inclined lines and the essentially differentcharacter of the symbols formed.

Pivotally mounted. upon a car D is a plate 11. By the word car is meantany vehiole adapted to travel in a fixed path. The roof of an electriccar or cab of a locomotive has been found to be peculiarly adapted forthe mounting of this plate. Plate 1 1 is preferably perforated, as shownat 12, to reduce the wind pressure against the same and provided withcorrugations, 13 for stiffening purposes and is given a smooth outersurface adapted to receive and retain an impression from the printingballs 9. Closely adjacent the plate 11 is located a valve 14 in thepiping 15 of the air braking system and the lever 16 of this valve isnormally in engagement with and adapted to be actuated by a lever 18fixed upon the shaft 19 of the plate. It will thus be seen that upon theoscillation of plate 11 the shaft 19 will be rotated within bearings 20and by means of levers 18 and 16, the valve 15 will be opened,permitting the escape of air from the braking system and thus applyingthe brakes. Various other means of applying the brakes by means of themovement of plate 11 will be readily suggested and the aboveconstruction is described as merely illustrative of one manner ofaccomplishing this object.

There is preferably mounted upon bracket 65 1 at a point near the pivotof lever 2 a call box 21. The preferred construction of this call boxforms no part of the present invention and may be of any desired typewherein a distinctive call is electrically sent to a distant stationupon the actuation of the crank thereof. Longitudinally journaled withinthe lever 2 is a shaft 22 having fixed thereto an arm 23 upwardlyprojecting through an opening in lever 2 and adapted to engage theactuating crank of call box 21. Fixed to the outer end of shaft 22 is adownwardly projecting arm 24 adapted to engage the beforementionedshoulder 8 upon the side member of the carriage C.

The operation of this embodiment of my invention is as follows :1Viththe parts in normal safety position as shown in Fig. 2, upon theactuation of the semaphore B to danger position, indicated in Fig. 1,the eccentric 3 above arm 4 is raised. The greater weight of the outerarm of lever 2 with carriage C causes this arm to fall as far as ispermitted by eccentric 3 and arm 4 and this movement changes thedownward inclination of the lever from an inward. to an outwarddirection, referring as before to support A. Carriage C, as a result ofthis change, moves from its normal position against shoulder 2 to aposition against shoulder 2 the shock of contact thereof being lessened,if desired, by a coiled spring 25. In its outer position the carriage Csuspends balls 9 directly in the path of plate 11 carried by the car forwhich the signal is set. Should the signal be disregarded and the carattempt to run past the same, the balls 9 will come into contact withthe upper portion of plate 11, leaving their distinctive mark thereonand rotating the plate into a horizontal plane, as indicated in Fig. 6.This movement, on account of the before-described relation of levers 18and 16, will also result in the application of the brakes upon the caror train. Also, the reaction of plate 11 upon balls 9 will causecarriage C to be swung about the axis of lever 2 in such manner that theshoulder 8 will engage arm 24, and, by means of shaft 22 and arm 23,actuate call box 21 and send a notification to the train despatchersoffice or other desired destination to the effect that the danger signalhas been passed. The apparatus then falls again into operative positionso that a following car would cause a repetition of the above series ofoperations. Upon the returning of the semaphore to a safety position thecarriage C will automatically roll inwardly against shoulder 2 and outof the path of the plates 11.

It will thus be seen that I have provided a simple, inexpensive andreliable safety device which is entirely automatic in action and doesnot depend in any way upon the cooperation of the engineer. Also, thefact that a danger signal has been passed will be conclusively evidencedby the plate upon the car,

which will indicate not only this fact but will also show which dangersignal was passed. The train despatcher, moreover, through the medium ofcall box 21, will be immediately notified that a danger signal has beenpassed and will know from the distinctive call which danger signal hasbeen passed, and may act accordingly. The call box, moreover, may beused independently from the remainder of the safety apparatus, as it maybe manually actuated by a member of the train crew and a message thussent to the train despatcher. Another marked advantage of this system isthat it may readily be applied with small and inexpensive alterations tovarious types of systems now in use.

Various changes and modifications will readily be suggested in the aboveembodiment of my invention. For example, the valve 14 may control theadmission of live steam or compressed air to positively apply the brakesinstead of releasing the air from the braking system of the type now ingeneral use. Another manifest modification would. be the substitution ofa wire or wires held taut across the track and provided with stops forthe form of lever shown in the draw ings. One end of such wire could beraised and lowered in accordance with the movement of the semaphore arm.Also, the recording mechanism may obviously be located within the carand merely the actuating means therefor exposed to the weather. It willalso be readily seen that various features of my invention have anindependent value, as the braking feature, the printing apparatus andthe call box mechanism may be used separately or in any combination onewith another. For these and other reasons I desire all features ofconstruction set forth in this description and the accompanying drawingsto be interpreted as illustrative and not in a limiting sense. I desireit also to be understood that the language used in the claims isintended to cover both the generic and specific features of theinvention which as a matter of language might be said to falltherebetween.
